Oracle used Lisp [1] in the UIs for their gen-2 cloud product. They eventually hit a wall hiring the kinds of people Oracle wanted to hire (few of whom wanted to learn an esoteric language), and made the tragic decision to move new development over to TypeScript (and port many of the key existing surfaces for ongoing maintainability). Mixed results on that. Many who were around for both the old and new code bases report that, while the old one took more effort to pick up, it was easier to trace data flow and is less prone to creating weird state bugs.
